Hi,
thanks for information, but I want to use AJAX functionality, so I can't use
normal submit (AJAX is faster and it keeps the page scroll position).
Listening to recName events doesn't help neither - the value is still null:
@EventListener(events="onchange", elements="recName")
public void onRefresh(IRequestCycle cycle) {
log.debug(getRecName()); // = null
}
This is the description of autoSubmit parameter of @EventListener:
"When components implementing IFormComponent are targeted they will normally
automatically cause a form submission to happen so that the property they
manage on your form is updated when your listener method is called - this
parameter can be used to disable the automatic submission of the enclosing
form."
... so I think the form should submit and the value of recName should be set
entered value, right?
Is there any difference between elements and targets parameters of
@EventListener?
Maybe I should move this thread to Tapestry forum.
I need to achieve something like this:
